Roughness of Interfacial Crack Front: Correlated Percolation in the Damage Zone
Jean Schmittbuhl, Alex Hansen, G. George Batrouni
We show that the roughness exponent zeta of an in-plane crack front slowly propagating along a heterogeneous interface embeded in a elastic body, is in full agreement with a correl…
Origin of the Universal Roughness Exponent of Brittle Fracture Surfaces: Correlated Percolation in the Damage Zone
Alex Hansen, Jean Schmittbuhl
We suggest that the observed large-scale universal roughness of brittle fracture surfaces is due to the fracture process being a correlated percolation process in a self-generated…
Heterogeneous Interfacial Failure between Two Elastic Blocks
G. George Batrouni, Alex Hansen, Jean Schmittbuhl
We investigate numerically the failure process when two elastic media, one hard and one soft that have been glued together thus forming a common interface, are pulled apart. We pre…
Elastic Response of Rough Surfaces in Partial Contact
G. George Batrouni, Alex Hansen, Jean Schmittbuhl
We model numerically the partial normal contact of two elastic rough surfaces with highly correlated asperities. Facing surfaces are unmated and described as self-affine with a Hur…
Distinguishing fractional and white noise in one and two dimensions
Alex Hansen, Jean Schmittbuhl, George Batrouni
We discuss the link between uncorrelated noise and Hurst exponent for one and two-dimensional interfaces. We show that long range correlations cannot be observed using one-dimensio…
Normal Stress Distribution of Rough Surfaces in Contact
Alex Hansen, Jean Schmittbuhl, G. George Batrouni +1
We study numerically the stress distribution on the interface between two thick elastic media bounded by interfaces that include spatially correlated asperities. The interface roug…
Anomalous roughening of wood fractured surfaces
Stephane Morel, Jean Schmittbuhl, Juan M. Lopez +1
Scaling properties of wood fractured surfaces are obtained from samples of three different sizes. Two different woods are studied: Norway spruce and Maritime pine. Fracture surface…
